Main Street in Fort Lee runs busy from morning through evening, and the green spaces along it are small, hard-working and seen by everybody. Certified Landscaping LLC keeps those lawns and grass strips in shape through the heat of July, when the Bergen County air goes thick and turf grows fast between cuts. The work is mowing, string-trimming the awkward corners, edging where grass meets concrete, and hauling the clippings off so nothing is left behind but a clean rectangle of green. Later, when the plane trees begin to let go, the fall cleanups start. It is plain work done on a schedule, in a town where everything faces the sidewalk.
